4. Replacement and Adjustment
Precautions
General
• Turn off the main power switch and unplug the machine before starting replacement.
Before turning off the main power switch, check that no mechanical component is operating. Mechanical
components may stop out of their home positions if you turn off the main power switch while they are
operating. The component may be damaged if you try to remove it when it is not in the home position.
Lithium Batteries
• Incorrect replacement of lithium battery(s) on the controller or on the fax unit poses risk of explosion.
Replace only with the same type or with an equivalent type recommended by the manufacturer.
Discard used batteries in accordance with the manufacturer’s instructions.
Halogen-free Cable
• Use extreme caution while handling cables.
To comply with local regulations, halogen-free cables are used in this machine. Halogen-free cables are
environment-friendly, but no stronger than conventional cables. These cables may be damaged in any of
the following cases:
• The cable is caught between hard objects such as brackets, screws, PCBs, and exterior covers.
• The cable is rubbed on a hard object such as brackets, screws, PCBs, and exterior covers.
• The cable is scratched with a hard object such as brackets, screws, PCBs, exterior covers,
screwdrivers, and fingernails.
Static Electricity
Always touch a grounded surface to discharge static electricity from your hands before you handle SD
cards, printed circuit boards, or memory boards.
